Question

我重启了Rails 4 VPS，Solr显然也关机了。我现在正在尝试启动Solr，但是当我运行以下RAILS_ENV=production bundle exec rake sunspot:solr:start时，我收到以下错误消息：

rake aborted!
Sunspot::Solr::Server::JavaMissing: You need a Java Runtime Environment to run the Solr server

(See full trace by running task with --trace)

奇怪的是安装了Java：

$ echo $JAVA_HOME
/usr/lib/jvm/java-6-openjdk-amd64/jre/bin/java
$ java -version
java version "1.6.0_31"
OpenJDK Runtime Environment (IcedTea6 1.13.3) (6b31-1.13.3-1ubuntu1~0.12.04.2)
OpenJDK 64-Bit Server VM (build 23.25-b01, mixed mode)

我不确定可能导致此行为的原因。有什么建议吗？

Answer 1

尝试添加PATH java所在的文件夹，如下所示：

export PATH=$PATH:/path/to/java/bin

这样java就可以从任何地方调用而无需指定文件夹。

在调用rake之前启动它解决了我的问题。

Rails 4：Solr抛出JavaMissing错误，但安装了Java
